You guys probably don't know the REAL reason David Lee Roth left Van Halen. Turns out his head got so big he could no longer get it through the doors of airplanes and buses, so he could no longer tour with the band. The final straw was when, during a performance of "Jump", his right leg hip joint ruptured and fused with the leg pointing straight up. Today he gets around on crutches, although the right leg sometime interferes with this.
Last I heard he had retired to an estate where he lined all the walls, ceilings, and floors with mirrors so that no matter where he was he could always catch a glimpse of his favorite person, himself. He spends his spare time designing hats with large slots on the right side of the brim.
